Feasibility Of Applying Motion Magnification In Subsurface Defect Detection For Concrete And Fiber-Reinforced Polymer Specimens, Nagavardhani Malineni

Graduate Theses, Dissertations, and Problem Reports (ETD)

Irrespective of size and complexity, every civil infrastructure needs certain scrutiny regarding its structural health to ensure its serviceability during its lifetime. In olden times such scrutiny was done with the aid of destructive testing methods using sensors that required cumbersome and expensive installations and led to the destruction of at least part of the tested specimen. However, in recent times, many non-destructive methods, such as acoustic emission testing, electromagnetic testing, and laser testing methods have emerged, leaving the specified tested specimen undisturbed. With the advancement in sensor technology like motion magnification and with the help of access to high-speed …

Utility Of An Emotion Coding System For Parent-Child Interaction Therapy With Toddlers, Christopher Kyle Owen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Numerous efficacious early interventions target and alter caregiver-child interactions to promote optimal social-emotional outcomes for young children (Bagner et al., 2014). However, research has primarily relied on the use of caregiver report to assess caregiver-child emotion-focused practices, revealing the need for a behavioral observation assessment (Zinsser et al., 2021). Preliminary evidence suggests that Parent-Child Interaction Therapy with Toddlers (PCIT-T) is a well-received and efficacious intervention for reducing disruptive behaviors, improving child internalizing and externalizing behavior, reducing parental stress, and increasing parental sensitivity (Kohlhoff et al., 2021; Kohlhoff, Cibralic, & Morgan, 2020). PCIT-T strives to train caregivers to interact with their …

A Randomized Controlled Trial Comparing Pcit-Toddler, Circle Of Security, And Waitlist Controls To Improve Child And Caregiver Emotion Regulation, Robin Choi Han

Graduate Theses, Dissertations, and Problem Reports (ETD)

Emotion regulation is an important developmental task during toddlerhood that is associated with positive psychosocial outcomes (Zeman et al., 2006). The development of adaptive emotion regulation during early childhood occurs largely within the context of a supportive caregiver-child relationship (Morris et al., 2007). Thus, parent-mediated interventions are a promising medium through which emotion regulation problems in toddlers can be treated. However, few interventions specifically designed to treat behavioral and emotion regulation difficulties are available for children in the toddler age range, and these interventions have yet to establish a solid evidence base supporting their efficacy. To fill this gap in …

State Estimation, Covariance Estimation, And Economic Optimization Of Semi-Batch Bioprocesses, Ronald Hunter Alexander

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the most critical aspects of any chemical process engineer is the ability to gather, analyze, and trust incoming process data as it is often required in control and process monitoring applications. In real processes, online data can be unreliable due to factors such as poor tuning, calibration drift, or mechanical drift. Outside of these sources of noise, it may not be economically viable to directly measure all process states of interest (e.g., component concentrations). While process models can help validate incoming process data, models are often subject to plant-model mismatches, unmodeled disturbances, or lack enough detail to track …

The Impact Of Fracture Properties On Adsorbed Gas Production From A Marcellus Shale Horizontal Well, Valcia Mildreth Vasco Bulule

Graduate Theses, Dissertations, and Problem Reports (ETD)

Abstract

In addition to the gas present in the pores of the rock, shale also contains gas in the adsorbed state within the surface of the organic matter within the formation. As the free gas is produced, the pressure in the reservoir depletes, causing the adsorbed gas to be released, complementing the gas production. At the same time, the pressure reduction leads to increase in the effective stress causing shale compaction. The shale compaction negatively impacts the permeability and hydraulic fracture conductivity. This study aimed to investigate the impact of hydraulic fracture characteristics on the adsorbed gas recovery and, ultimately, …

Meiotic Recombination In Zea Mays And Its Contribution To Genetic Diversity, Jasmine Elizabeth Freeman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Meiotic recombination plays a vital role in shaping genome evolution by introducing genetic diversity necessary for natural selection. Recombination rates exhibit extensive variation within and between species, occurring in specific regions known as hotspots and coldspots along individual chromosomes. Maize, with its well-characterized genome, provides an excellent model for studying the nonrandom pattern of meiotic recombination. While retrotransposon activity contributes to significant intergenic variation in maize inbred lines, the genic space remains conserved in terms of gene order and sequence. To investigate recombination activity in the Bz1/Sh1 region, the maize haplotypes W22 and B73, which share genetic backgrounds but differ …

Multimodal Neuron Classification Based On Morphology And Electrophysiology, Aqib Ahmad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Categorizing neurons into different types to understand neural circuits and ultimately brain function is a major challenge in neuroscience. While electrical properties are critical in defining a neuron, its morphology is equally important. Advancements in single-cell analysis methods have allowed neuroscientists to simultaneously capture multiple data modalities from a neuron. We propose a method to classify neurons using both morphological structure and electrophysiology. Current approaches are based on a limited analysis of morphological features. We propose to use a new graph neural network to learn representations that more comprehensively account for the complexity of the shape of neuronal structures. In …
